Active clinical trials for "Hypersensitivity"

Background and Rationale For patients with Immunoglobulin E (IgE)-mediated food allergy, the current management includes identification of the causative food and avoidance. Specifically, among young children, cow's milk allergy is the most common food allergy, occurring in as many as 2-3%. Given the prevalence of milk and the difficulty to avoid it in the diet, the investigators aim to investigate the safety and efficacy of oral immunotherapy for cow's milk allergy. Main Objective The primary objective is to study the efficacy of milk oral immunotherapy. Target Population Children aged six to 17 years with a history of cow's milk allergy will be recruited from The Children's Hospital of Philadelphia Allergy clinical offices for the investigators study.

The Primary Objective of the study is to develop a customized regimen for oral immunotherapy that reflects what the subject is allergic in a clinically significant way (i.e., the offending food allergen is defined as a food allergen with a positive skin test or positive specific IgE and a positive DBPCFC). Therefore, the investigators prefer that both single and multiple food allergy subjects are included in the study.

Study to evaluate the safety, tolerability, antitumor activity, and pharmacology of MEDI-573 in combination with an aromatase inhibitor (AI) in adult subjects with HR+, HER2-negative MBC.

The study will evaluate the dose response of immunotherapy against grass pollen allergy using the recombinant grass pollen vaccine BM32. Efficacy will be analyzed by: skin prick testing grass pollen inhalation challenge antibody responses. In addition, the safety of subcutaneous application of BM32 will be evaluated.

Periodontal instrumentation aims to remove plaque and calculus from the root surface. Both manual and ultrasonic instruments have been used for such decontamination; however, establishing a healthy periodontium can result in adverse effects, such as dentin hypersensitivity. The aim of this study was to evaluate the effects of hand or ultrasonic instrumentation on dentin hypersensitivity in patients undergoing non-surgical periodontal treatment. For this controlled clinical trial of a "split mouth" design, 14 patients were selected with homologous teeth in the incisor to premolar region and probing depth ≥ 5 mm on the buccal aspect of the teeth. One side (control) was instrumented with hand instruments and the other side (test) with ultrasonic instruments. Dentin hypersensitivity was assessed in the baseline and during the follow 4 weeks after treatment, with a periodontal probe scratching the root surface and with an air jet. The patient's response was detected by a visual analog scale (VAS) of 10 cm.

Cat allergy is an increasingly prevalent condition, affecting 10-15% of patients with allergic rhinoconjunctivitis. Cat-PAD is a novel, synthetic, allergen derived peptide desensitising vaccine currently being developed for treatment of cat allergy. At present, the efficacy of immunotherapy (peptide or otherwise) can only be established at the conclusion of therapy. No reliable predictive biomarkers of clinical efficacy currently exist. Identification of surrogate biomarkers of clinical efficacy, would facilitate clinical development of peptide immunotherapy vaccines, in addition to providing an improved understanding of the underlying molecular mechanisms of efficacy, thus providing new leads for therapeutic intervention.

Grass pollen allergens are recognised as a major cause of allergic diseases in humans and animals. Worldwide, at least 40% of allergic patients are sensitised to grass pollen allergens and between 50-90% of hayfever or seasonal allergy sufferers are allergic to grass pollen. ToleroMune Grass is a novel, synthetic, allergen-derived peptide desensitising vaccine, currently being developed for the treatment of grass allergy. This study will look at the efficacy, safety and tolerability of three doses of ToleroMune Grass in grass allergic subjects following challenge with with grass in an Environmental Exposure Unit (EEU).

The objective of this study is to evaluate the effect of mindfulness-based cognitive therapy (MBCT) on physical symptoms attributed to chemical exposures, psychological distress, illness worry, quality of life, and illness perceptions in patients suffering from multiple chemical sensitivity (MCS). Furthermore, a secondary objective is to evaluate whether a possible symptom reduction is mediated by an increased level of mindfulness. The primary hypothesis is that the self-reported severity of MCS symptoms and the degree to which chemical exposures causes symptoms and the impact on daily life will be significantly improved in the MBCT treatment group as compared to the control group.

The purpose of this study is to assess the immunological differences between three RagweedMATAMPL treatment arms compared to placebo with respect to immunoglobulin levels. In addition, the study will assess the reduced allergenicity of modified Ragweed Pollen contained in RagweedMATAMPL compared to unmodified native allergen using skin prick testing.
